I give up I really do. I must be the most HDM aware person in the world, daily damp dusting, duvet washed every month at 60 degrees or over, pillows changed very 6 months, matress in funky allergy recommened cover,no soft toys, wood floors, damp dusting, dust extractor (don't bother it does not work) sofa steam cleaned once every 6 months, books encased or dusted daily with one of those special dusters that the dust glues too even my medications are all kept in tidy plastic boxes on to prevent dust build up around then . Yet I still can't get my HDM RAST below 100. Where do the little beggers hide.
